The Energy Yield from Fermentation Is Lower Than from Respiration

question 2

Multiple Choice

The energy yield from fermentation is lower than from respiration because

• A) fermentation uses NAD+, not NADP+.
• B) respiration completely oxidizes glucose to CO₂, resulting in greater generation of NADH and thus ATP.
• C) respiration uses the TCA cycle, which has many steps that directly produce ATP or GTP.
• D) fermentation shunts much of the carbon from glucose to biosynthesis.
• E) fermentation relies on the glyoxylate bypass, which bypasses ATP production.
